      Hello friends,

       

      We are using TI AM3351 processor with WiFi/BT module BCM43455 over SDIO interface.

       

      TI SDK : ti-processor-sdk-linux-am335x-evm-04.01.00.06

      Linux Kernel is 4.9.41-ge3a80a1c5c

      Wlan driver is brcmfmac :

      brcmfmac: F1 signature read @0x18000000=0x15264345

      Firmware version = wl0: Mar  1 2015 07:29:38 version 7.45.18 (r538002) FWID 01-6a2c8ad4)

       

      When device is connected using wpa_supplicant, to a AP of 5GHz, it is getting disconnected repeatedly after every reconnection with the 5GHz AP.

       

      Attached log I'm seeing when wpa_supplicant is run in debug mode: log.txt

       

      As I can see in the log, an event NL80211_CMD_DISCONNECT is received, I suspect this event is causing this issue.

       

      But strangely this issue is not observed with the 2.5GHz WiFi APs, Working fine with 2.5GHz APs.

       

      Can you guys help me resolving this issue.

       

      Help is much appreciated.

       

      Thanks,

      aniket jesu
